Public bug reported: SRU Justification
Impact: We recently backported SECCOMP_USER_NOTIF_FLAG_CONTINUE in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1847744. On a kernel that supports SECCOMP_FILTER_FLAG_NEW_LISTENER but not SECCOMP_USER_NOTIF_FLAG_CONTINUE the selftests currently fail to compile. The reason is that the ifndef for SECCOMP_USER_NOTIF_FLAG_CONTINUE is placed under the ifndef for SECCOMP_FILTER_FLAG_NEW_LISTENER. Fix: The ifndef for SECCOMP_USER_NOTIF_FLAG_CONTINUE was placed under the ifndef for the SECCOMP_FILTER_FLAG_NEW_LISTENER feature. This will not work on systems that do support SECCOMP_FILTER_FLAG_NEW_LISTENER but do not support SECCOMP_USER_NOTIF_FLAG_CONTINUE. So move the latter ifndef out of the former ifndef's scope. Regression Potential: Limited to seccomp selftests. Test Case: Compile the selftests on a kernel that supports SECCOMP_FILTER_FLAG_NEW_LISTENER but does not support SECCOMP_USER_NOTIF_FLAG_CONTINUE and see that compilations succeeds. Target Kernels: All current LTS kernels with access to a 5.0 kernel.
